Experienced Computer trainer having worked in IT sector for 20 years.

An if-else statement controls conditional branching. Statements in the if-branch are executed only if the condition evaluates to a nonzero value (or true ). If the value of condition is nonzero, the following statement gets executed, and the statement following the optional else gets skipped.

We can use the else statement with the if statement to execute a block of code when the condition is false. The if-else statement consists of two blocks, one for false expression and one for true expression.
